As shown in fig. 1-16, the embodiment of the present application provides a rotary connection mechanism, which includes a baffle plate set, a moving structure set, and a torsion structure set. The barrier group includes a first barrier 100, a second barrier 200, and an intermediate barrier 300, the first barrier 100 being rotatably connected with respect to the intermediate barrier 300, the second barrier 200 being rotatably connected with respect to the intermediate barrier 300. The motion structure group comprises a first motion structure and a second motion structure which is symmetrically arranged with the first motion structure, the first motion structure is positioned at the first end of the baffle group, and the second motion structure is positioned at the second end of the baffle group. The moving structure group is used for controlling the first baffle 100 and the second baffle 200 to be in a first relative position, and the first baffle 100, the middle baffle 300 and the second baffle 200 form a plane. The moving structure group is used for controlling the first baffle 100 and the second baffle 200 to be in a second relative position, and the first baffle 100 and the second baffle 200 are opposite and form a target angle. The torsion structure group is positioned at one side of the middle baffle plate; the torsion structure group comprises a first torsion structure and a second torsion structure, the first torsion structure is matched with the first movement structure, and the second torsion structure is matched with the second movement structure. The torsion structure group provides torsion support at the first relative position and the second relative position through the movement structure group, and provides acting force for switching between the first relative position and the second relative position through the movement structure group under the action of external force.

The rotary connection mechanism provided in the embodiment of the present application controls the first baffle 100 and the second baffle 200 to switch between the first relative position and the second relative position through the moving structure group, and the torsion structure group is used for providing torsion support at the first relative position and the second relative position through the moving structure group. And, under the action of external force, the torsion structure group provides acting force through the switching of the first baffle plate 100 and the second baffle plate 200 between the first relative position and the second relative position by the movement structure group. With the above arrangement, the switching operation of the first barrier 100 and the second barrier 200 between the first relative position and the second relative position is achieved, and the state of the first barrier 100 and the second barrier 200 in the first relative position and the second relative position can be supported.

The first baffle 100 and the second baffle 200 are in a first relative position, and the first baffle 100, the intermediate baffle 300 and the second baffle 200 form a plane. That is, the first barrier 100, the intermediate barrier 300 and the inner side surface (surface for facing the screen) of the second barrier 200 are positioned on the same plane. The torsion support is provided at the first relative position through the torsion structure group, so that the stability of the first baffle plate 100 and the second baffle plate 200 at the first relative position is ensured, the first baffle plate 100, the middle baffle plate 300 and the second baffle plate 200 are all used for providing effective support for the flexible bending part of a folding screen (such as a flexible display touch screen), the support effect is ensured, and the operation of operators is facilitated. When the first baffle 100 and the second baffle 200 are switched from the first relative position to the second relative position, an external force is provided by an operator or equipment, and an external force is provided for the moving structure group to switch between the first relative position and the second relative position by the torsion structure group, so that the moving structure group controls the first baffle 100 and the second baffle 200 to switch between the first relative position and the second relative position. The first baffle 100 and the second baffle 200 are in a second relative position, and the first baffle 100 and the second baffle 200 are opposite and form a target angle, so that the first baffle 100 and the second baffle 200 can rotate relative to the middle baffle 300, and a flexible bending part of a folding screen (such as a flexible display touch screen) between the first baffle 100 and the second baffle 200 is subjected to bending guide. Providing torsional support in the second relative position by the set of torsional structures ensures stability of the first and second baffles 100, 200 in the second relative position so as to ensure that the folded screen (e.g., flexible display touch screen) achieves the intended target screen bend angle. When the first baffle 100 and the second baffle 200 are switched from the second relative position to the first relative position, an external force is provided by an operator or equipment, and the torsion structure group provides an acting force for switching the first baffle 100 and the second baffle 200 between the second relative position and the first relative position through the movement structure group under the action of the external force, so that the movement structure group controls the first baffle 100 and the second baffle 200 to switch between the second relative position and the first relative position. The bending operation is facilitated by the combined action of the moving structure group and the torsion structure group. In the first relative position, the first baffle 100, the middle baffle 300 and the second baffle 200 form a plane, so that the plane plays a role in supporting a folding screen (such as a flexible display touch screen); in the second relative position, the first baffle 100 and the second baffle 200 are opposite and are at a target angle, so that the probability of crease occurrence on the folding screen is reduced on the basis of bending of the folding screen (such as a flexible display touch screen), and the usability of the folding screen is ensured.

Because the motion structure group includes first motion structure and the second motion structure that sets up with first motion structure symmetry, first motion structure is located the first end of baffle group, and the second motion structure is located the second end of baffle group. Wherein, the first end of the baffle group is one same side end of the first baffle 100, the second baffle 200 and the middle baffle 300, and the second end of the baffle group is the other same side end of the first baffle 100, the second baffle 200 and the middle baffle 300. Through above-mentioned setting for the motion structure group is located the outside of baffle group, in first relative position and second relative position, and the motion structure group all is located the tip of baffle group, can not cause the influence to the baffle group in first relative position and second relative position switching, also can not occupy the baffle group in the ascending size of thickness, on the basis of the whole thickness size demand of rotation coupling mechanism when having reduced first relative position and second relative position, guaranteed folding screen's angle of buckling, reduced the probability that appears the crease on the folding screen, further ensured folding screen's performance.

And, avoided the space of the back of rotation coupling mechanism (the one side that middle baffle 300 was kept away from folding screen), on the basis of arranging torsion structure group, can also set up other parts, like connecting parts such as the flexible printed circuit board of connecting electronic equipment's first body and second body, also can be in the space arrangement between the one side that middle baffle 300 kept away from folding screen and shell, make things convenient for the overall arrangement setting.

As shown in fig. 9, the intermediate baffle 300 includes a first intermediate baffle section 310, a second intermediate baffle section 320, and a third intermediate baffle section 330 for ease of assembly and for optimal layout. The first intermediate baffle section 310 and the second intermediate baffle section 320 are connected to the third intermediate baffle section 330 by connecting screws 340. A connection member such as a flexible printed circuit board may be located between the third intermediate barrier section 330 and the housing of the electronic device. The first torsion structure is located on the outside (side facing away from the folding screen) of the first intermediate baffle section 310 and the second torsion structure is located on the outside (side facing away from the folding screen) of the second intermediate baffle section 320.

The first end and the second end of the baffle group are respectively two ends of the baffle group. Wherein the arrangement direction of the first end and the second end of the barrier group is perpendicular to the arrangement direction of the first barrier 100, the second barrier 200 and the intermediate barrier 300. The first motion structure includes a first partial component; the first part includes a first connecting piece 411, a first connecting arm 412, a first connecting rod 413, and a first moving track piece 414. The first connecting piece 411 is used for fixedly connecting with a first body of the electronic device; the first connecting arm 412 is a connecting arm fixedly connected with the first main rotating shaft 511 of the first torsion structure, and the first connecting piece 411 is slidably connected with the first connecting arm 412; the first end of the first connecting rod 413 is rotatably connected to the body housing of the rotary connection mechanism through a first shaft core (not shown); the second end of the first connecting rod 413 is rotatably connected with the first connecting piece 411 through the second core 416; a first moving track member 414 is fixedly arranged with the first connecting member 411, the first moving track member 414 being adapted to control switching of the first shutter 100 between the first relative position and the second relative position.

As shown in fig. 7, the body housing of the rotary connection mechanism includes a torsion housing covering the torsion structure set. Taking the first torsion structure as an example, the first torsion structure 500 is covered by a first torsion housing 311, a first vertical end plate 312 is disposed at an end of the first torsion housing 311, and a first connecting rod 413 and a second connecting rod 423 are rotatably connected with the first vertical end plate 312.

Similarly, the second end of the first connecting rod 413 is rotatably connected to the first connecting member 411 through the second core 416, and the second end is simply rotatably connected to the first connecting member without relative torsion.

Taking the first part of the first moving structure as an example, as shown in fig. 1 and 3, in the process of switching from the first relative position to the second relative position, under the action of an external force, the first connecting piece 411 fixedly connected to the first body of the electronic device drives the first connecting arm 412 to rotate, and the first end of the first connecting rod 413 rotates relative to the body housing of the rotating connecting mechanism through the first shaft core (not shown), the second end of the first connecting rod 413 rotates relative to the first connecting piece 411 through the second shaft core 416, and the first connecting piece 411 slides relative to the first connecting arm 412. A first moving track member 414 is fixedly arranged with the first connecting member 411, the first moving track member 414 being adapted to control switching of the first shutter 100 between the first relative position and the second relative position. That is, by the combination of rotation and sliding of the respective parts in the first partial member, the relative interference of the respective parts in the first partial member is avoided; the first moving track 414 drives the first baffle 100 to rotate relative to the middle baffle 300, so as to switch the first baffle 100 from the first relative position to the second relative position.

During the switching of the first shutter 100 from the first relative position to the second relative position, due to the action of the torsion structure set, a synchronous rotation of the second shutter 200 with respect to the intermediate shutter 300 is achieved. That is, during the switching of the first barrier 100 to the second relative position at the first relative position, the second barrier 200 is synchronously switched to the second relative position at the first relative position.

The first moving track member 414 has an inclined slideway, one side of the first baffle 100 is rotationally connected with the middle baffle 300, and the other side of the first baffle 100 is slidably matched with the inclined slideway, so that the first baffle 100 is switched between the first relative position and the second relative position by combining the movement of the first moving track member 414.

Further, the first moving structure includes a second partial component, and the second partial component disposed in mirror image with the first partial component includes a second connection member 421, a second connection arm 422, a second connection rod 423, and a second moving rail member 424. That is, the first connecting member 411 is disposed in mirror image with the second connecting member 421 for fixedly connecting with the first body of the electronic device. The second connecting arm 422 is disposed in mirror image with the first connecting arm 412, and is fixedly connected to the second main shaft 521 of the first torsion structure, and the second connecting member 421 is slidably connected to the second connecting arm 422. The first connecting rod 413 and the second connecting rod 423 are arranged in a mirror image mode, and the first end of the second connecting rod 423 is rotationally connected with the body shell of the rotary connecting mechanism through a third shaft core; the fourth end of the second connecting rod 423 is rotatably connected to the second connecting member 421 through a fourth shaft 426. The second moving track member 424 is mirror-image to the first moving track member 414, wherein the second moving track member 424 is fixedly disposed with the second connecting member 421, and the second moving track member 424 is used for controlling the switching of the second shutter 200 between the first relative position and the second relative position. Wherein the first connecting member 411, the first connecting arm 412, the second connecting member 421 and the second connecting arm 422 form a first set of moving structures of the first moving structure; the first set of motion structures is used for transmitting the torsion provided by the main rotating shafts (the first main rotating shaft 511 and the second main rotating shaft 521) of the first torsion structure.

The first end of the second connecting rod 423 is rotationally connected with the body shell of the rotational connecting mechanism through the third shaft core, and the first end and the second end are only rotationally connected without relative torsion. Similarly, the fourth end of the second connecting rod 423 is rotationally connected to the second connecting member 421 via the fourth shaft 426, and the fourth end is simply rotationally connected to the second connecting member, without relative torsion.

That is, in the first set of moving structures of the first moving structure, the first connecting arm 412 is fixedly connected with the first main rotating shaft 511 of the first torsion structure, the second connecting arm 422 is fixedly connected with the second main rotating shaft 521 of the first torsion structure, a gear set is arranged between the first main rotating shaft 511 and the second main rotating shaft 521 of the first torsion structure, and in the rotating process of the first main rotating shaft 511, the second main rotating shaft 521 is driven to rotate in opposite directions and synchronously, so that the torque force provided by the main rotating shaft of the first torsion structure is transmitted, and the torsion support is conveniently provided for the first baffle 100 and the second baffle 200 at the first relative position and the second relative position.

The first connecting rod 413, the first moving track member 414, the second connecting rod 423 and the second moving track member 424 form a second set of moving structures of the first moving structure, and the second set of moving structures are used for controlling the first baffle 100 and the second baffle 200 to switch between the first relative position and the second relative position in a linkage manner.

Since the first connecting arm 412 and the second connecting arm 422 rotate in opposite directions and synchronously through the first main rotation shaft 511, the first connecting piece 411 is fixedly connected with the first moving track piece 414, and the second connecting piece 421 is fixedly connected with the second moving track piece 424, so that the first connecting piece 411 drives the first moving track piece 414 to rotate along the rotation shaft of the first connecting arm 412 and slide along the extending direction of the first connecting arm 412 (the direction from one end of the first connecting arm 412 to the other end thereof) during the rotation of the first connecting arm 412 and the second connecting arm 422. That is, in the process of switching between the first relative position and the second relative position, the first moving rail 414 rotates and slides, and similarly, the second moving rail 424 moves (rotates and slides) synchronously, thereby switching between the first and second relative positions of the first and second shutters 100 and 200 is achieved.

The center line of the mirror image may be a plane in which the center line of the middle barrier 300 is located, and the first barrier 100 and the second barrier 200 are symmetrically disposed with respect to the plane. The first end of the second connecting rod 423 is rotationally connected with the body shell of the rotational connecting mechanism through the third shaft core, and the first end and the second end are only rotationally connected without relative torsion. Similarly, the fourth end of the second connecting rod 423 is rotationally connected to the second connecting member 421 via the fourth shaft 426, and the fourth end is simply rotationally connected to the second connecting member, without relative torsion.

By combining the rotation and the sliding of each part in the second part, the relative interference of each part in the second part is avoided; and, the second moving track member 424 drives the second baffle 200 to rotate relative to the middle baffle 300, so as to realize the switching of the second baffle 200 from the first relative position to the second relative position.

Likewise, the second moving structure is symmetrically arranged with the first moving structure. Because the first moving structure is located at the first end of the baffle group and the second moving structure is located at the second end of the baffle group, the second moving structure moves synchronously with the first moving structure, so as to improve the movement stability of the first baffle 100 and the second baffle 200 in the baffle group.

That is, the second motion structure includes a third partial component and a fourth partial component, wherein the third partial component is mirrored from the fourth partial component. Similarly, the center line of the mirror image may be a plane in which the center line of the intermediate baffle 300 is located, and the first baffle 100 and the second baffle 200 are symmetrically disposed with respect to the plane.

The third part includes a third connecting member 431, a third connecting arm 432, a third connecting rod 433 and a third moving track member 434, where the third connecting member 431 drives the third connecting arm 432 to rotate, and a first end of the third connecting rod 433 rotates relative to the body housing of the rotating connecting mechanism through a fifth shaft (not shown), a second end of the third connecting rod 433 rotates relative to the third connecting member 431 through a sixth shaft 436, and the third connecting member 431 slides relative to the third connecting arm 432. The third moving rail 434 is fixedly disposed with the third link 431. The third track of movement 434 is used to control the switching of the first shutter 100 between the first relative position and the second relative position. That is, the first and third partial members are located at both ends of the first shutter 100, respectively, and the first and third partial members move synchronously, thereby realizing a synchronous operation for switching the first shutter 100 between the first and second relative positions.

As above, the fourth part includes the fourth connecting member 441, the fourth connecting arm 442, the fourth connecting rod (not shown) and the fourth moving track member 444, the fourth connecting member 441 drives the fourth connecting arm 442 to rotate, and the first end of the fourth connecting rod (not shown) rotates relative to the body housing of the rotating connecting mechanism through the seventh shaft core (not shown), the second end of the fourth connecting rod rotates relative to the fourth connecting member 441 through the eighth shaft core, and the fourth connecting member 441 slides relative to the fourth connecting arm 442. The fourth moving rail 444 is fixedly provided with the fourth connecting member 441. The fourth moving track 444 is used to control the switching of the second shutter 200 between the first relative position and the second relative position. That is, the second and fourth partial members are located at both ends of the second barrier 200, respectively, and the second and fourth partial members move synchronously, thereby realizing a synchronous operation for switching the second barrier 200 between the first and second relative positions.

Similarly, the second track member 424, the third track member 434, and the fourth track member 444 each have inclined ramps.

One side of the first baffle 100 is rotatably connected with the middle baffle 300, while two ends of the other side of the first baffle 100 are respectively in sliding fit with the inclined slide ways of the first moving track member 414 and the inclined slide ways of the third moving track member 434, and the first baffle 100 is switched between the first relative position and the second relative position by combining the movements of the first moving track member 414 and the third moving track member 434.

One side of the second baffle 200 is rotatably connected with the middle baffle 300, while two ends of the other side of the second baffle 200 are respectively in sliding fit with the inclined slide ways of the second moving track member 424 and the inclined slide ways of the fourth moving track member 444, and the second baffle 200 is switched between the first relative position and the second relative position by combining the movement of the second moving track member 424 and the fourth moving track member 444.

To increase the overall strength of the rotational coupling, a first coupling edge member 600 is provided between the first and third movement track members 414, 434. Likewise, there is a second connecting edge member 700 between the second track member 424 and the fourth track member 444.

In order to avoid screen damage caused by hard extrusion of the screen, it is necessary to realize that the relative movement rate of the body (the first body and the second body) of the electronic device is different from the bending rate of the screen.

Taking the first part as an example, since the first connecting piece 411 is fixedly connected to the first body of the electronic device, the first connecting arm 412 is fixed to the first main shaft 511 and rotates along the axis of the first main shaft 511, and thus the rotation rate of the first main shaft 511 is the rotation rate of the body (the first body and the second body) of the electronic device.

Since the axes of the first main shaft 511, the first shaft core and the second shaft core 416 are not collinear. Therefore, in the process that the first connecting arm 412 rotates along the axis of the first main rotating shaft 511, the first connecting arm 412 and the first connecting piece 411 slide relatively, the positional relationship between the axis of the first main rotating shaft 511 and the axis of the second shaft 416 changes, and the other side of the first baffle 100 slides along the inclined slide way of the first moving track piece 414, so that the rotation speed of the first baffle 100 relative to the middle baffle 300 is different from the rotation speed of the first connecting arm 412, and further the bending speed of the first baffle 100 guiding the folding screen is different from the folding speed of the body (the first body and the second body) of the electronic device, and the screen damage caused by hard extrusion of the body of the electronic device is avoided through the differential speed between the two.

The third main rotating shaft and the fourth main rotating shaft of the second torsion structure are the same as above. The third connecting arm 432 is fixedly connected with a third main shaft of the third torsion structure, the fourth connecting arm 442 is fixedly connected with a fourth main shaft of the second torsion structure, and a transmission component (such as a gear shaft or a gear) is arranged between the third main shaft and the fourth main shaft of the second torsion structure. Wherein, the axis of the third main shaft, the axis of the fifth shaft core and the axis of the sixth shaft core 436 are not collinear. As above, the shaft groups of the first main shaft 511, the first shaft core and the second shaft core 416 and the shaft groups formed by the third main shaft, the fifth shaft core and the sixth shaft core 436 are respectively located at two ends of the first baffle 100, so that the rotation speed of the first baffle 100 is different from the rotation speed of the first body of the electronic device.

Similarly, the axes of the second main shaft 521, the third shaft core and the fourth shaft core 426 are not collinear, and the axes of the fourth main shaft, the seventh shaft core and the eighth shaft core are not collinear. By the above arrangement, the difference in the rotation rate of the second barrier 200 from the rotation rate of the second body of the electronic apparatus is achieved.

Preferably, the first baffle 100 and the second baffle 200 are in the first relative position, and the axis of the first main shaft 511, the axis of the first shaft core, and the axis of the second shaft core 416 form a first triangle; the first baffle 100 and the second baffle 200 are at the second relative position, and the axle center of the first main rotating shaft 511, the axle center of the first axle core and the axle center of the second axle core 416 form a second triangle; the process of switching the first barrier 100 and the second barrier 200 between the first relative position and the second relative position, the movement of the mating surface of the first barrier 100 and the movement of the mating surface of the second barrier 200 avoid pressing the flexible bending portion of the flexible display touch screen of the electronic device.

In this embodiment, the distance between the axis of the first main shaft 511 and the axis of the first shaft core is unchanged, and the distance between the axis of the first shaft core and the axis of the second shaft core 416 is unchanged. During the switching between the first relative position and the second relative position, the distance between the axis of the first main rotation shaft 511 and the axis of the second shaft core 416 changes. Wherein the angle of the largest angle in the first triangle is smaller than the angle of the largest angle in the second triangle, and therefore the second triangle is an overall flat triangle.

Through the above arrangement, the rotation speed of the first main rotating shaft 511 is smaller than that of the first baffle 100 relative to the middle baffle 300, and when the rotation angle of the first main rotating shaft 511 is 90 °, the rotation angle of the first baffle 100 relative to the middle baffle 300 is greater than 90 °, so that the first baffle 100 and the second baffle 200 approach each other along the direction away from the middle baffle 300, and the flexible bending portion of the flexible display touch screen of the electronic device is prevented from being extruded.

Wherein the mating surface of the first baffle is the surface of the first baffle, which is contacted with the folding screen (flexible display touch screen). The mating surface of the second baffle is the surface of the second baffle which is contacted with the folding screen (flexible display touch screen).

The first main rotation shaft 511 is not coaxial with the first connection shaft by which the first barrier 100 rotates with respect to the intermediate barrier 300. In order to reduce the overall thickness (thickness after folding) of the electronic device when the first and second shutters 100 and 200 are at the second relative positions as much as possible, the middle bending angle (inner bending angle) of the flexible bending portion of the folding screen (flexible display touch screen) is satisfied, and the occurrence of creases due to excessively small screen bending angles is avoided, the first connecting shaft of the first shutter 100 rotating relative to the middle shutter 300 is located at the outer side of the first main rotating shaft 511. With the above arrangement, the distance between the first connecting shaft of the first barrier 100 rotating with respect to the intermediate barrier 300 and the second connecting shaft of the second barrier 200 rotating with respect to the intermediate barrier 300 is expanded as much as possible, and since the moving structure group is located at the end of the barrier group and the torsion structure group is located at the back surface (the surface facing away from the folding screen) of the barrier group, the intermediate bending angle can be increased as much as possible by expanding the distance between the first connecting shaft and the second connecting shaft as much as possible. The outer side of the first main rotating shaft 511 is a side of the first main rotating shaft 511 away from the folding screen.

Similarly, the second connection shaft, through which the second barrier 200 rotates with respect to the intermediate barrier 300, is located outside the second main rotation shaft 521. The outer side of the second main rotating shaft 521 is the side of the second main rotating shaft 521 away from the folding screen.

For a symmetrical arrangement, the first connection axis of rotation of the first barrier 100 with respect to the intermediate barrier 300 is located outside the third main rotation axis. The second connection shaft, through which the second barrier 200 rotates with respect to the intermediate barrier 300, is located outside the fourth main rotation shaft. In this embodiment, in order to achieve that the flexible bending portion of the folding screen (flexible display touch screen) forms a droplet-shaped structure after bending, the first connection shaft of the first barrier 100 rotatably connected with respect to the middle barrier 300 is located at a first side of the middle barrier, and the second connection shaft of the second barrier 200 rotatably connected with respect to the middle barrier 300 is located at a second side of the middle barrier 300. The first moving track member 414 is engaged with a distal end of the first shutter 100 corresponding to the first connecting shaft; the second moving rail 424 is engaged with a distal end of the second shutter 200 corresponding to the second coupling shaft. Wherein the first baffle 100 and the second baffle 200 are in a second relative position, the distal end of the first baffle 100 is in close proximity to the distal end of the second baffle 200. That is, the first barrier 100 and the second barrier 200 are in the second relative position, and the distance between the first edge of the intermediate barrier 300 to the second edge thereof is greater than the distance between the distal end of the first barrier 100 and the distal end of the second barrier 200. The distance from the first edge of the middle baffle 300 to the second edge thereof is also the distance from the first connecting end of the first baffle 100 rotatably connected to the middle baffle 300 to the second connecting end of the second baffle 200 rotatably connected to the middle baffle 300.

In addition, in the closed state of the electronic device (the first baffle 100 and the second baffle 200 are in the second relative position), since the first portion and the second portion of the folding screen are respectively connected with the first body and the second body of the electronic device, the distal end of the first baffle 100 is close to the distal end of the second baffle 200, and the first portion and the second portion of the folding screen are close to each other, so that the gap (the gap between the first portion and the second portion of the folding screen) in the closed state of the electronic device is effectively reduced.

Wherein the flexible folded portion (third portion) of the folding screen is located between the first portion and the second portion.

As shown in fig. 11-16, the first torsion structure includes a first main shaft 511, a gear set, and a second main shaft 521. The first main rotation shaft 511 includes a first profile gear; the second main rotation shaft 521 includes a second profile gear. The first torsion structure is matched with the first special-shaped gear and the second special-shaped gear through the gear set to realize synchronous rotation, and the first torsion structure is matched with the first group of limiting points 301 and the second group of limiting points 302 through the first special-shaped gear to realize a first opening and closing angle of the electronic equipment corresponding to the first relative position and a second opening and closing angle of the electronic equipment corresponding to the second relative position.

In this embodiment, the first special gear has a first limit portion 513 and a second limit portion 512, and the second special gear has a third limit portion 523 and a fourth limit portion 522.

The first opening and closing angle is preferably 180 °.

As shown in fig. 15 and 16, when the first baffle 100 and the second baffle 200 are at the second relative positions, the second limiting portion 512 of the first special-shaped gear is in limiting contact with the other side of the first set of limiting points 301, and the fourth limiting portion 522 of the second special-shaped gear is in limiting contact with the other side of the first set of limiting points 301, so that the first baffle 100 and the second baffle 200 are respectively rotated relative to the middle baffle 300, and the first baffle 100 and the second baffle 200 are opposite and form a target angle, and then the second relative position corresponds to the second opening and closing angle of the electronic device. The second opening and closing angle is preferably 0 °.

The first special-shaped gear and the first group of limiting points and the second special-shaped gear and the second group of limiting points can also respectively realize the limiting of the first opening and closing angle and the second opening and closing angle of the electronic equipment. That is, the first opening and closing angle of the electronic device is realized by the limitation of the first special-shaped gear and the first group of limiting points, and the synchronous rotation is realized by the cooperation of the gear set, the first special-shaped gear and the second special-shaped gear, so that the limitation is also realized by the second special-shaped gear. And the second opening and closing angle of the electronic equipment is realized by limiting the second special-shaped gear and the second group of limiting points, and the first special-shaped gear also realizes limiting as the gear group is matched with the first special-shaped gear and the second special-shaped gear to realize synchronous rotation.
